Description

Technical Field

[0001] This utility model relates to the technical field of children's stroller equipment, specifically to a children's stroller sunshade adjustment device. Background Technology

[0002] As a common tool for infants and toddlers, strollers rely heavily on their sunshades, which are crucial for protecting them from direct sunlight and the elements. Existing stroller sunshade adjustment mechanisms often employ snap-on or Velcro structures, which have the following drawbacks: First, the adjustment levels are unclear, and misalignment can easily occur when the snaps engage, causing the sunshade to shift. Second, after prolonged use, the snaps or Velcro wear down, reducing adjustment stability and even posing a risk of the sunshade falling off. Third, most adjustment mechanisms only apply force to one side, making it easy for the sunshade to tilt during adjustment and preventing smooth adjustment. Therefore, we propose a new stroller sunshade adjustment mechanism. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a stroller sunshade adjustment device. It employs a V-shaped elastic positioning component that engages with a groove. Utilizing the self-centering characteristic of the V-shaped structure, it ensures automatic centering of the elastic positioning component during engagement, avoiding positioning deviations and solving the problem of inaccurate positioning in existing snap-on structures. The elastic positioning component deforms and contracts under force, and its resetting and engaging process is seamless. Furthermore, the simultaneous adjustment on both sides further enhances the smoothness of adjustment, ensuring that both ends of the sunshade move synchronously and preventing tilting.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] The stroller sunshade adjustment device is characterized by:

[0006] A slide rail is fixedly mounted on the stroller body, and a number of grooves are spaced apart along the extension direction perpendicular to the slide rail.

[0007] A support member is slidably connected to the slide rail. The support member has a cavity inside, and one side of the support member is used to connect to one end of the awning.

[0008] An elastic positioning element is assembled into the cavity of the bearing member;

[0009] One end of the elastic positioning element is fixed to the inner wall of the cavity of the carrier, and the other end extends out of the cavity and is embedded in the groove to form a positioning; when the carrier is pushed to move along the slide rail, the elastic positioning element is squeezed and deformed by the side wall of the groove and retracts into the cavity, releasing the positioning.

[0010] Preferably, each end of the sunshade is connected to a support member, and each end of the stroller body is fitted with a slide rail adapted to the support member.

[0011] Preferably, the groove has a V-shaped cross-section.

[0012] Preferably, one side of the support member is detachably fixed to one end of the awning, and the bottom of the support member is slidably engaged with the slide rail.

[0013] This utility model provides an adjustable sunshade for a children's stroller. It has the following beneficial effects:

[0014] The elastic positioning component with a V-shaped structure cooperates with the groove. Utilizing the self-centering property of the V-shaped structure, it ensures that the elastic positioning component automatically centers when it is inserted, avoiding positioning deviation and solving the problem of inaccurate positioning of the existing snap-on structure. The elastic positioning component deforms and contracts under force and resets and inserts without jamming during the process. In addition, it is combined with the synchronous adjustment on both sides to further improve the smoothness of adjustment and ensure that the two ends of the sunshade move synchronously to avoid tilting.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] See attached document Figure 1-3A stroller sunshade adjustment device includes a slide rail 1, which is fixedly mounted on a preset position of the stroller frame along the length of the stroller body. The extension direction of the slide rail 1 is consistent with the adjustment trajectory of the sunshade. Several positioning grooves are spaced apart on the side wall of the slide rail 1 perpendicular to the extension direction of the slide rail 1. The cross-section of the grooves is V-shaped.

[0024] The support member 2 has an internal cavity structure. One side of the support member 2 is detachably fixed to one end of the sunshade. The bottom of the support member 2 is slidably engaged with the slide rail 1 and can move back and forth along the extension direction of the slide rail 1. An elastic positioning member 3 is fixedly assembled in the cavity of the support member 2. The cross-sectional shape of the elastic positioning member 3 is adapted to the V-shaped structure of the groove, and the elastic positioning member 3 has elastic reset capability and can restore its initial shape after being deformed by force.

[0025] One end of the elastic positioning element 3 is fixedly connected to the inner wall of the cavity of the bearing element 2, and the other end extends out of the cavity and is embedded in the groove of the slide rail 1, forming a positioning constraint on the bearing element 2. When an external force pushes the bearing element 2 to move along the slide rail 1, the elastic positioning element 3 is squeezed by the side wall of the groove and undergoes elastic deformation, shrinking into the cavity of the bearing element 2 and releasing the positioning constraint. When the bearing element 2 moves to the next groove position, the elastic positioning element 3 returns to its initial shape under its own elastic force, extends out of the cavity again and is embedded in the groove, completing the repositioning of the bearing element 2, thereby realizing the adjustment of the position of the awning.

[0026] Furthermore, in some embodiments, to improve the synchronicity and stability of the sunshade adjustment, a support member 2 is respectively installed at both ends of the sunshade, and a slide rail 1 is fixedly installed at both ends of the stroller body (corresponding to the two ends of the sunshade). Each slide rail 1 slides and cooperates with the corresponding support member 2 to form two sets of slide rail 1-support member 2, ensuring that the two ends of the sunshade move synchronously along the corresponding slide rail 1, and avoiding the sunshade tilting or getting stuck during the adjustment process.

[0027] Furthermore, the elastic positioning element 3 is made of thermoplastic elastomer (TPE) or reinforced nylon material, and the included angle of its V-shaped structure is 60°-90°. The included angle of the groove is consistent with the included angle of the elastic positioning element 3.

[0028] Furthermore, the slide rail 1 is made of aluminum alloy extrusion molding, and its surface is anodized. There are 2-5 grooves along the length of the slide rail 1 to meet the multi-level adjustment requirements of the awning.
